MatchKing rifle bullets are super-accurate bullets with very thin jackets and are held to exacting tolerances in diameter and weight. Their accuracy has been acclaimed worldwide and they have been used to win more target competitions than all target bullets from other manufacturers combined. Weight retention is held to within +/- 0.3 grain. Sierra has enhanced a segment of the MatchKing line by adding the acetal resin tip, thus crowning the Tipped MatchKing (TMK) bullet line. The major advantage of adding a tip to the bullet is the reduction of drag, producing a more favorable ballistic coefficient. The Tipped MatchKing (TMK) bullet is an excellent choice for Palma and F-Class (FTR / F Open) matches, as well as 3-Gun and various other competitions. Box of 500, .30 155 grain Polymer Tip Boat Tail.
